Christian M. Verhagen, Elkhart, Ind., assignor to a The Adlake Company, Chicago, 111., a corporation of Illinois Application January 15, 1937, Serial-No. 120,763 '5 Claims. (01. 189-76) The object of this invention is to provide a vertically slidable sash in which side rails of improved construction are employed. A sash with this new side rail construction is quite weathertight, affords a large area of vision, is amply strong even in the larger sizes, is attractive in blue to produce the sash;

One form of the invention is presented herein for the purpose of exempliiication, but it will of course be appreciated that the invention is susceptible of embodiment in other structurally .modifled forms coming equally within the scope of the appended claims. 1

In the accompanying drawings: Fig. 1 is a perspective view of one side of a sash V constructed in accordance with the invention; Fig. 2 is an edge view of the sash;

Fig. 3 is a face view of one of the upper corners of thesash} Y Fig. 4 is a horizontal section, taken on the line oi'Fig. 3; Fig. 5 is a vertical section, taken on the line 8-5 of Fig. 3;

' Fig. -6 is a horizontal section, taken on the line 6-6 of Fla-3;

Fig. Tis a face view of one of the lower corners,

'of the sash:

Fig. 8 is a horizontalsection, taken ,on the line l! ofFig. 7; and Fig. 9 is a vertical section, taken on'the line '98 of Fig. 7. As will be observed in the drawings, the sash ll consists of a pane of glass ii which is sup-.

ported at its edges in rubber glazing strips I2 set into grooves in top, bottom and side rails l3, l4 and I5. The top and bottom rails I3 and I4 are of ordinary construction, but the side rails ii (of which only one is shown) are of special construction.

Each of the side rails ii of thesash consists of twosheet metal channel strips i6 and I1 and a pile fabric strip ll. Themetal strips l6 and H are nested together in tightly fitting relation,

sides of the strip i6 and the sides of the strip ii. The strip i1 is provided adjacentthe fabric covered edges of the strip IS with outturned flanges 20 which terminate approximately. flush with the The 5 channel. 22 which is present in the inner metal strip ll serves as a glazing groove and is occu-' pied by the glazing strip l2 on the vertical edge of the glass II.

The upper and lower ends of this composite l0 rail structure are attached to the ends of the top and bottom rails i3 and I by means of solid metal blocks 23 and 24. These blocks are fixedly secured in the hollow ends of the top and bottom rails and-project therefrom into the channel 22 15 in the inner strip ll. The projecting portions of the blocks 23 and 24 fit tightly within the, channel and are detachably held in position by means of screws 25 which pass through the back of the rail into the blocks. The outturned flanges 20 20 on the edges of ,the inner strip I! are drawn up against the cut ends of the top and bottom rails at 26, giving a nicely'finished appearance to the joints in the corners of the sash. The

metal channel strips i6 and I1 may be secured 25,

vided along its lower edge with a rubber sealing 30 I strip 28 which is shaped to conform to an inclined sill, and the lower end 'of the side rail l5 projects downwardly on the outside of the sash a short distance beyond the lower outer edge of the bottomrail i4, terminating just above the lower 35 surface of the sealing strip 28 at approximately the same angle as the latter, with the end of the sealing strip disposed within the angularly cut end of the side 'rail. The fabric strip l8 of the side rail preferably projects downwardly a little 40 beyond the lower edges of the metal channel strips l6 and II in order to provide a soft sealing fillet 29 at the outer-comer.

If desired, thin sheet metal plates 30 of generally triangular shapemay be positioned against 45 the outer and inner surfaces of the. glass II at the corners of the sash, within the grooves in the glazing strips l2, in order to give a rounded eflfect to the corners.

The improved side rail which constitutes this 50 invention permits of a sash which is not only inexpensive to manufacture and easy to assemble but is light in weight, quite rigid and affords a large area of vision. The tightly nested association of the sheet metal channel strips i6 and H, combined with the spread of the outturned flanges III on the inner strip ll, prevents any appreciable distortion of the side rails under the stresses to which sash are ordinarily subiected in service. The outturned flanges 2. also act as protective baiiles for the pile II of the fabric strips, diverting air currents, rain and foreign particles from the sealing portions of the rails.

If desired, the rivets 21 may be omitted in order to render the metal strip it which carries the fabric strip ll readily detachable from the metal strip il, whereby to facilitate the replacement of the fabric strip.

A sash constructed in accordance with the invention is especially applicable to car and bus windows, where lightness combined with strength and rigidity are especially important factors.

I claim:

1. In a sash, a grooved side rail consisting of two metal channel strips which are nested together, and a cushioning strip which is positioned about the back and sides of the outer metal strip with its edges clamped between the sides of the outer metal strip and the sides of the inner metal strip. 1

2. In a sash, a grooved side rail consisting of two sheet metal channel strips which are nested together, and a cushioning strip which is positioned about the back and sides of the outer metal strip with its edges clamped between the sides of the outer metal strip and the sides of the inner metal. strip, the inner metal strip being provided beyond the edges of the outer metal strip with outturned flanges.

3. In'a sash, the combination with a pane of glass, and top and bottom rails on the uppelfand lower edges of the glass, of metal side rails of outwardly flanged U-shaped cross section into which the ends of the top and bottom rails and the side edges of the glass project.

4. In a sash, the combination with a pane of glass, and top and bottom rails on the upper and lower edges of the glass, of sheet metal side rails of outwardly flanged U-shaped cross section into which the ends of the top and bottom rails and the side edges of the glass project, and fabric covered sheet metal bearing strips of U-shaped cross section fitted over the side rails in tightly engaged reinforcing relation thereto.

5. In a sash, the combination with a pane of glass, and top and bottom rails on the upper and lower edges of the glass, of metal side rails of U-shaped cross section and rubber glazing strips on the edges of the glass, said glazing strips being positioned ,in grooves provided in all of the rails, and said side rails extending the full height of the sash beyond the upper and lower ends of the glazing strips on the side edges of the glass in the side rails, with the ends of the top and bottom rails projecting into and secured to the bottoms of the grooves in the side rails immediately above and below the ends of the glazing strips in the side rails.
